Note that IE and Firefox return different values for offsetWidth due to bounding box differences, but both behave as above for the nested case. 187326 1 cshempel 2010-02-03 05:44:50 -0800 I'm also experiencing this bug 239326 2 marcoos+bwo 2010-06-17 03:56:31 -0700 I can also see this bug in Safari 5 and recent Chrome 6 dev builds. 268720 3 gdennis 2010-08-24 12:41:29 -0700 I see this in Chrome 5 and Chrome 6 beta. 407683 4 niall.smart 2011-05-22 10:54:31 -0700 Reproduced in Chrome 11.0.696.68 485370 5 cxescalona 2011-10-17 12:21:01 -0700 Confirmed on Chromium 14.0.835.163 and Safari 5.0 (7533.16). Problem extended to multiple IMG elements into a div and another div with css IMG: width:auto; height:100%; Containerdiv: width:noSet; height:noSet; ContainerContainerDiv: width:300px; height:300px; Structure: Div class ContainerContainerDiv Div class ContainerDiv IMG IMG IMG javascript: alert(IMG_DOM_ELEMENT.offsetWidth) //Result: 0 1887150 6 ahmad.saleem792 2022-07-27 13:29:49 -0700 I am able to reproduce this bug using attached test case in Safari 15.6 on macOS 12.5 and it shows "test2.offsetWidth: 0" - which is what this bug about. Here are results from other browsers: ** Firefox Nightly 105 ** test1.offsetWidth: 96 test2.offsetWidth: 1277 ** Chrome Canary 106 ** test1.offsetWidth: 96 test2.offsetWidth: 1287 (There was another bug where Chrome was different from Firefox with just 10 px and it was about scrollbar - just want to add some note here) ** Safari 15.6 on macOS 12.5 ** test1.offsetWidth: 96 test2.offsetWidth: 0 Just find updated results.
